چکیده

Currently, the aluminum alloys are utilized more in level of all industries for different applications; furthermore, need high-strength making innovative components. For those reasons, many researchers hope to prepare hybrid metal matrix composites at various composition levels. In this experimental work, we intended such as alloy 7079 with reinforcement ZrO2 + Si3N4 through stir-casting process. Major findings optimize process, can be continually conduct wear test and evaluate microhardness stir-casted specimens. Optimization process parameters is a preliminary work research by Taguchi tool. The chosen % (0%, 4%, 8%, 12%), agitation speed (450 rpm, 500 550 600 rpm), time (15 min, 20 min. 25 30 min), molten temperature (700°C, 750°C, 800°C, 850°C). prepared materials tested analysis analysis, Pin-on-Disc tester Vickers hardness tester, respectively. Wear optimized, minimum rate evaluated, also worn-out surfaces examined SEM analysis.

Tribological performance of Graphene/Carbon nanotube hybrid reinforced Al2O3 composites

Tribological performance of the hot-pressed pure Al2O3 and its composites containing various hybrid contents of graphene nanoplatelets (GNPs) and carbon nanotubes (CNTs) were investigated under different loading conditions using the ball-on-disc method. Benchmarked against the pure Al2O3, the composite reinforced with a 0.5 wt% GNP exhibited a 23% reduction in the friction coefficient along wit...
